'Chuck' preview: No more secrets ... except this one

Whatever Shaw (
Brandon Routh) was talking about at the end of last week's
"Chuck," it sure has Sarah on edge.

So much so that, despite her recent conversation with Chuck (
Zachary Levi) about not keeping secrets anymore, Sarah (
Yvonne Strahovski) is now charging off on a solo mission. She's not saying what it is or who she's meeting, but as you can see in this clip from Friday's (Dec. 30) episode, "Chuck vs. the Baby," she's taking a good amount of weaponry.

Chuck is a little distraught at the idea of Sarah keeping a secret, but he's also thinking on his feet. She may not want to tell her husband everything that's going on, but Carmichael Industries will give her all the support she needs -- no questions asked.

Based on the look on Sarah's face right at the end of the clip, we doubt Chuck's ploy works. But it's a nice effort nonetheless. "Chuck," featuring guest stars
Cheryl Ladd (as Sarah's mom) and
Tim DeKay (as her former handler), airs at 8 p.m. ET Friday.
